World under-14 girls’ champion M. Mahalakshmi shocked Grandmaster Sahaj Grover in the second round of the Apollo Engineering College-Commonwealth chess championship here on Friday.

In another big upset, Madhurima Shekhar shocked National champion G. Akash in 40 moves.

Sahaj won a pawn early and kept picking up pawns at regular intervals.

However, Mahalakshmi continued to attack and won using her queen, rook and bishop. Sahaj had misplaced his queen and Mahalakshmi capitalised on this error to win in 41 moves.

Top seed Tiviakov won both his games while fifth seed Oleksienko crushed S.R. Harikrishna in just 19 moves by threatening mate and the two rooks at the same time to win.
